10 Moons People Can Actually Live On

One day it will be an amazing scientific accomplishment when we colonize and bring life to a moon like Saturn's icy Enceladus.

5. Triton
Photographs and data sent back from the Voyager 2 spacecraft back in August of 1989 showed that the surface of Triton, Neptune’s largest moon, was made up of nitrogen ice and rock. The suspicion of liquid water being hidden beneath the surface was raised. Even though the moon has an atmosphere, it would be pretty much the same as if it didn’t have one because of how thin it is. The average temperature on the moon is an unbelievable -391 degrees Fahrenheit, making it the coldest body in the entirety of our solar system.
4. Mimas
Also known as the “Death Star” moon and for good reason. Mimas is one of Saturn’s icy and rocky moons. Mimas might have an ocean located beneath its cold and unwelcoming -looking surface, which may possibly be better adapted for life. Close study of the Cassini footage by scientists shows that Mimas looks to rock back and forth as it went around on its orbit. This could imply activity underneath its surface. However, scientists were very wary with what they found, stating that there hadn’t been any other signs that point to geological activity. They merely stated that if an ocean was discovered, the moon could definitely be a candidate for being colonized. It’s believed that the theoretical ocean would be about 15 to 18 miles below the surface. If the rocking movement that supports this theory of an ocean proves to be false, then the movement is mostly likely because of a misshapen core due to the strong gravitational pull caused by Saturn’s rings
3. Callisto
Exactly the same size as the planet Mercury, Callisto is Jupiter’s second largest moon that looks like it has a large liquid ocean hidden within its icy surface. The surface of Callisto mainly made up of craters and what are basically fields of ice. Callisto also has a relatively thin atmosphere consisting of carbon dioxide. Research that already been performed has suggested that this atmosphere is being filled up again and again by carbon dioxide that is released from below the surface because it is too thin to stay in place. Collected data implies the chance that oxygen could also be actively present inside of the atmosphere, but there would need to be further tests to confirm if this theory holds true. Callisto is positioned in a safe enough space from Jupiter that the giant planet’s radiation levels would be very mild.
2. Ganymede
Ganymede happens to be Jupiter’s largest moon and like other masses, in our solar system, it could potentially prove to have water trapped underneath its surface. If you were to compare it to other ice-covered moons, Ganymede’s surface is believed to be relatively thin and should be much easier to break through. This moon also happens to be the only moon with its own gravitational field that creates its own auroras, like the ones that are produced here on earth. Their pattern in movement also leads scientists to theorize there is an ocean trapped underneath the surface. Because of Ganymede’s thin oxygen atmosphere, it is too thin to support our life but maybe enough to support terraforming. Back in 2012, the European Space Agency got the okay to go ahead and launch a mission to go and explore Ganymede and two other of Jupiter’s moons, Europa and Callisto. The operation is scheduled to launch in 2022 and reach the moon 10 years later. Out of the three moons to be explored, scientists believe that Ganymede will have the best environment to study and potentially support life, if possible.
1. The Moon
The first moon that mankind would colonate would, of course, be the earth’s very own moon. It’s been described as a good “dress rehearsal” for potential colonization missions in the future because of how close it is to earth compared to all the other moons. Earlier in March of this year, there was a story that was going around that this type of operation could be carried out within the next 10 years or so. NASA astrobiologist Chris McKay is one of the individuals whose onboard with making this mission come to fruition. His opinion is that other missions to the moon have failed because of the high cost, but his team has a plan that requires little compared to previous missions. Although NASA’s current focus is to get humans to land on Mars, McKay says that that won’t come to light until they can first get to the moon and set up permanent bases there first.

Triton Is The Strangest Moon In Our Entire Solar System

In 3.5 billion years, Triton will eventually come in contact with Neptune and break into pieces.

Why Does Neptune's Moon, Triton, Orbit Backwards?

Neptune's largest moon, Triton, orbits the opposite direction of all other moons in our solar system, and no one is sure why. No, Triton is not a "Death Star" or an artificial object, but it may not have originated near Neptune.

Triton (moon) - Video Learning - WizScience.com

"Triton" is the largest moon of the planet Neptune. It was discovered on October 10, 1846, by English astronomer William Lassell. It is the only large moon in the Solar System with a retrograde orbit, an orbit in the opposite direction to its planet's rotation. At 2700 km in diameter, it is the seventh-largest moon in the Solar System. Because of its retrograde orbit and composition similar to Pluto's, Triton is thought to have been a dwarf planet captured from the Kuiper belt. Triton has a surface of mostly frozen nitrogen, a mostly water-ice crust, an icy mantle and a substantial core of rock and metal. The core makes up two-thirds of its total mass. Triton has a mean density of 2.061 g/cm3 and is composed of approximately 15–35% water ice.
Triton is one of the few moons in the Solar System known to be geologically active. As a consequence, its surface is relatively young, with a complex geological history revealed in intricate cryovolcanic and tectonic terrains. Part of its crust is dotted with geysers thought to erupt nitrogen. Triton has a tenuous nitrogen atmosphere less than 1/70,000 the pressure of Earth's atmosphere at sea level.
Triton was discovered by British astronomer William Lassell on October 10, 1846, just 17 days after the discovery of Neptune.
A brewer by trade, Lassell began making mirrors for his amateur telescope in 1820. When John Herschel received news of Neptune's discovery, he wrote to Lassell suggesting he search for possible moons. Lassell did so and discovered Triton eight days later. Lassell also claimed to have discovered rings. Although Neptune was later confirmed to have rings, they are so faint and dark that it is doubtful that he actually saw them.

Voyager 2 Encounters Neptune and Triton 1989 NASA JPL

https://en.wikipedia.org/wiki/Voyager_2
Voyager 2 is a 722 kg (1,592 lb) space probe launched by NASA on August 20, 1977 to study the outer Solar System and eventually interstellar space. It was actually launched before Voyager 1, but Voyager 2 was sent on a different trajectory and arrived at Jupiter and Saturn after Voyager 1. Voyager 2 has been operating for 37 years, 11 months and 14 days as of 3 August 2015, and the Deep Space Network is still receiving its data transmissions.
At a distance of 108 AU (1.62×1010 km) from the Sun as of April, 2015, it is one of the most distant man-made objects (along with Voyager 1, Pioneer 10 and Pioneer 11). Voyager 2 is part of the Voyager program with its identical sister craft Voyager 1, and is in extended mission, tasked with locating and studying the boundaries of the Solar System, including the Kuiper belt, the heliosphere, and interstellar space.
The primary mission ended December 31, 1989, after encountering the Jovian system in 1979, Saturnian system in 1981, Uranian system in 1986, and the Neptunian system in 1989. It is still the only spacecraft to have visited the two outer giant planets Uranus and Neptune. The probe is now moving at a velocity of 15.4 km/s (about 55,470 km/hr) relative to the Sun, as of December, 2014...
Encounter with Neptune
Voyager 2's closest approach to Neptune occurred on August 25, 1989. Because this was the last planet of the Solar System that Voyager 2 could visit, the Chief Project Scientist, his staff members, and the flight controllers decided to also perform a close fly-by of Triton, the larger of Neptune's two originally known moons, so as to gather as much information on Neptune and Triton as possible, regardless of Voyager 2's departure angle from the planet. This was just like the case of Voyager 1's encounters with Saturn and its massive moon Titan.
Through repeated computerized test simulations of trajectories through the Neptunian system conducted in advance, flight controllers determined the best way to route Voyager 2 through the Neptune-Triton system. Since the plane of the orbit of Triton is tilted significantly with respect to the plane of the ecliptic, through mid-course corrections, Voyager 2 was directed into a path several thousand miles over the north pole of Neptune. At that time, Triton was behind and below (south of) Neptune (at an angle of about 25 degrees below the ecliptic), close to the apoapsis of its elliptical orbit. The gravitational pull of Neptune bent the trajectory of Voyager 2 down in the direction of Triton. In less than 24 hours, Voyager 2 traversed the distance between Neptune and Triton, and then observed Triton's northern hemisphere as it passed over its north pole.
The net and final effect on the trajectory of Voyager 2 was to bend its trajectory south below the plane of the ecliptic by about 30 degrees. Voyager 2 is on this path permanently, and hence, it is exploring space south of the plane of the ecliptic, measuring magnetic fields, charged particles, etc., there, and sending the measurements back to the Earth via telemetry.
While in the neighborhood of Neptune, Voyager 2 discovered the "Great Dark Spot", which has since disappeared, according to observations by the Hubble Space Telescope. Originally thought to be a large cloud itself, the "Great Dark Spot" was later hypothesized to be a hole in the visible cloud deck of Neptune.
Neptune's atmosphere consists of hydrogen, helium, and methane. The methane in Neptune's upper atmosphere absorbs the red light from the Sun, but it reflects the blue light from the Sun back into space. This is why Neptune looks blue...

Ice Geysers on Triton

This is a computer animation of cryovolcanism of Triton, the largest moon of Neptune. These icy geysers were observed by the Voyager 2 spacecraft - or rather, the spacecraft photographed the long stains that these features left on the landscape. It is thought that solar heating vaporises nitrogen below a translucent surface, until the pressure builds up enough to force an eruption. The gas picks up dust and other material, making the plumes visible. They reach a height of some eight kilometres above the surface of Triton, whereupon they are caught up in high-altitude winds and blown sideways.
This work was completed in 3DS Max, with Photoshop being used to create the landscape of Triton by enhancing pre-existing NASA imagery. It was commissioned to appear in a documentary.

Voyager - Triton

NASA's Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. Like an old film, Voyager’s historic footage of Triton has been 'restored' and used to construct the best-ever global color map of that strange moon. The map, produced by Paul Schenk, a scientist at the Lunar and Planetary Institute in Houston, has also been used to make a movie recreating that historic Voyager encounter, which took place 25 years ago, on August 25, 1989. The new Triton map has a resolution of 600 meters per pixel. The colors have been enhanced to bring out contrast but are a close approximation to Triton’s natural colors. Voyager’s 'eyes' saw in colors slightly different from human eyes, and this map was produced using orange, green and blue filter images. In 1989, most of the northern hemisphere was in darkness and unseen by Voyager. Because of the speed of Voyager's visit and the slow rotation of Triton, only one hemisphere was seen clearly at close distance. The rest of the surface was either in darkness or seen as blurry markings. The production of the new Triton map was inspired by anticipation of NASA's New Horizons encounter with Pluto, coming up a little under a year from now. Among the improvements on the map are updates to the accuracy of feature locations, sharpening of feature details by removing some of the blurring effects of the camera, and improved color processing. Although Triton is a moon of a planet and Pluto is a dwarf planet, Triton serves as a preview of sorts for the upcoming Pluto encounter. Although both bodies originated in the outer solar system, Triton was captured by Neptune and has undergone a radically different thermal history than Pluto. Tidal heating has likely melted the interior of Triton, producing the volcanoes, fractures and other geological features that Voyager saw on that bitterly cold, icy surface. Pluto is unlikely to be a copy of Triton, but some of the same types of features may be present. Triton is slightly larger than Pluto, has a very similar internal density and bulk composition, and has the same low-temperature volatiles frozen on its surface. The surface composition of both bodies includes carbon monoxide, carbon dioxide, methane and nitrogen ices. Voyager also discovered atmospheric plumes on Triton, making it one of the known active bodies in the outer solar system, along with objects such as Jupiter's moon Io and Saturn's moon Enceladus. Scientists will be looking at Pluto next year to see if it will join this list. They will also be looking to see how Pluto and Triton compare and contrast, and how their different histories have shaped the surfaces we see. Although a fast flyby, New Horizons' Pluto encounter on July 14, 2015, will not be a replay of Voyager but more of a sequel and a reboot, with a new and more technologically advanced spacecraft and, more importantly, a new cast of characters. Those characters are Pluto and its family of five known moons, all of which will be seen up close for the first time next summer. Triton may not be a perfect preview of coming attractions, but it serves as a prequel to the cosmic blockbuster expected when New Horizons arrives at Pluto next year.

Top 10 Bizarre Moons in our Solar System

Top 10 Bizarre Moons in our Solar System
Our solar system is made up of the Sun and its nine planets (eight really, since Pluto got the boot). The planets get so much attention that it's easy to overlook the fact that there are a lot of other interesting things in our solar system — like moons. And a lot of them are just as interesting as the planets they orbit.

NASA Hubble spots New Neptune Moon

Neptune has fourteen known moons, including the newly discovered moon. The largest moon of Neptune is Triton, discovered by William Lassell on October 10, 1846; it's moons are named for minor water deities in Greek mythology. Inward of Triton are seven regular satellites, Neptune also has six outer irregular satellites.
Orbits of Neptune moons:
"This diagram shows the orbits of several moons located close to the planet Neptune. All of them were discovered in 1989 by NASA's Voyager 2 spacecraft, with the exception of S/2004 N 1, which was discovered in archival Hubble Space Telescope images taken from 2004 to 2009. The moons all follow prograde orbits and are nestled among Neptune's rings (not shown).
The outer moon Triton was discovered in 1846 — the same year the planet itself was discovered. Triton's orbit is retrograde, suggesting it is a captured Kuiper Belt object and therefore a distant cousin of Pluto. The inner moons may have formed after Triton's capture several billion years ago."

Location of Neptune New Moon:
"This composite Hubble Space Telescope picture shows the location of a newly discovered moon, designated S/2004 N 1, orbiting the giant planet Neptune, nearly 3 billion miles from Earth.
The moon is so small (no more than 12 miles across) and dim, it was missed by NASA's Voyager 2 spacecraft cameras when the probe flew by Neptune in 1989. Several other moons that were discovered by Voyager appear in this 2009 image, along with a circumplanetary structure known as ring arcs.
Mark Showalter of the SETI Institute discovered S/2004 N 1 in July 2013. He analyzed over 150 archival Neptune photographs taken by Hubble from 2004 to 2009. The same white dot appeared over and over again. He then plotted a circular orbit for the moon, which completes one revolution around Neptune every 23 hours.
The black-and-white image was taken in 2009 with Hubble's Wide Field Camera 3 in visible light. Hubble took the color inset of Neptune on August 19, 2009."

New Moon Orbiting Neptune Discovered

An astronomer studying archived images of Neptune taken by the Hubble Space Telescope has found a 14th moon orbiting the planet, NASA said on Monday (July 15).
Estimated to be about 12 miles (20 km) in diameter, the moon is located about 65,400 miles (105,251 km) from Neptune.
Astronomer Mark Showalter, with the SETI Institute in Mountain View, California, was searching Hubble images for moons inside faint ring fragments circling Neptune when he decided to run his analysis program on a broader part of the sky.
Follow-up analysis of other archived Hubble images of Neptune verified the object was a moon.
Neptune's largest moon, Triton, was discovered in 1846, just days after the planet itself was found. Nereid, Neptune's third largest moon was found in 1949.

The distant Sun appears at the upper-left and the blue crescent of Neptune right of centre. Using the CRIRES instrument on ESO's Very Large Telescope, a team of astronomers has been able to see that the summer is in full swing in Triton's southern hemisphere.

Neptune Moons

Neptune is the eighth planet from the Sun in our Solar System. Named for the Roman god of the sea, it is the fourth-largest planet by diameter and the third-largest by mass. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 Earth masses and not as dense. On average, Neptune orbits the Sun at a distance of 30.1 AU, approximately 30 times the Earth-Sun distance. Its astronomical symbol is , a stylized version of the god Neptune's trident.
Discovered on September 23, 1846, Neptune was the first planet found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed by Johann Galle within a degree of the position predicted by Urbain Le Verrier, and its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining 12 moons were located telescopically until the 20th century. Neptune has been visited by only one spacecraft, Voyager 2, which flew by the planet on August 25, 1989.
Neptune has 13 known moons. The largest by far is Triton, discovered by William Lassell just 17 days after the discovery of Neptune itself. It took about one hundred years to discover the second natural satellite, Nereid. Triton is massive enough to have achieved hydrostatic equilibrium, and would be considered a dwarf planet if it were in direct orbit about the Sun. Triton has a very unusual orbit that is circular but retrograde and inclined. Inward of Triton are six regular satellites, which all have prograde orbits that are not greatly inclined with respect to Neptune's equatorial plane. Some of these orbit among Neptune's rings.
Neptune also has six outer irregular satellites, including Nereid, whose orbits are much farther from Neptune, have high inclinations, and are mixed between prograde and retrograde. Two natural satellites discovered in 2002 and 2003, Psamathe and Neso, have the largest orbits of any natural satellites discovered in the Solar system to date. They take 25 years to orbit Neptune at an average of 125 times the distance between Earth and the Moon. Neptune has the largest Hill sphere in the solar system, owing primarily to its large distance from the Sun; this allows it to retain control of such distant moons.
Neptune's moons are named for aquatic personages in Greek and Roman mythology, many of them after Nereids, in keeping with Neptune's position as god of the sea.
Triton was discovered by William Lassell in 1846, seventeen days after Neptune was discovered. Nereid was discovered by Gerard P. Kuiper in 1949. In 1981 Larissa was first observed by Harold J. Reitsema, William B. Hubbard, Larry A. Lebofsky and David J. Thole.
No further moons were found until Voyager 2 flew by Neptune in 1989. Voyager 2 recovered Larissa and discovered five new inner moons, bringing the total of known moons of Neptune to eight.
In 2002 and 2003 telescopic surveys found five additional outer moons from Earth observatories bring the total to thirteen. The five new outer moons are Halimede, Sao, Psamathe, Laomedeia, and Neso.
